The plugin can not be activated because it produces a fatal error.

Hello andrebraselmann,

Today I’ve upgraded from CyberSyn to CyberSEO Lite, but soon after the upgrade, it was not possible to activate the Plugin, and on return of the error I discovered that this variable was undefined (cybersyn.php at line 37 ):

$ csyn_banner = cseo_file_get_contents (‘https://www.cyberseo.net/info/CyberSEO/ad-lite.php?site=’. urlencode (site_url ()));

So I deleted this line on my own and the Plugin could be activated again and it’s running fine.

I have the similar problem. After update I just can see blank page. When I go to cPanel and delete plugin folder, site works again.

Crashed three sites..apparently doesn’t like to play with other plugins…

Crashed my site as well after update, both admin and frontend. Deactivating plugin brought site up. Cannot activate now due to fatal error. Will try @pulpapp’s workaround.

Pleas make sure to update your copy of CyberSEO Lite to the latest available version.

Issue was caused by 6.0 Version 6.0.3 is able to be activated. The issue appears resolved.

Thank you.

Getting the same error as indicated earlier.

Did you update your copy of CyberSEO Lite to version 6.03?

yes…absolutely…cleaned cache as well.

What the message says?

When I activate the plugin (newest version) I get the following error (it goes away when I deactivate the plugin)

These are not errors but just warnings and notices that have no relation to CyberSEO Lite (CyberSyn). They all caused by other 3rd-party plugins.

The the code crashes, it give you a message which starts with “Error:“.

Email me with your site’s URL: cyberseo@cyberseo.net

I deactivated the plugin.

The errors only appear when your plugin is activated so it is causing the problem.

I sent you an email.

> The errors only appear when your plugin is activated so it is causing the problem.

Once again: not errors but warnings and notices in nimble-portfolio and schema-and-structured-data-for-wp plugins that use deprecated functions, undefined array indexes etc. The debug messages reveal all the information on what is wrong and where it is located. There are no such mistakes in my code.

You don’t see those warnings and notices only because WP_DEBUG in your wp-config.php is set to FALSE which means no error messages will be shown.

You should delete the plugin via Plugins -> Installed Plugins WordPress panel and re-install it again.

or

Download the plugin here, unzip and upload it into your /wp-content/plugins folder manually.
